I applied through an employee referral. The process took 2 months. I interviewed at Amazon (Londres, Angleterre) in Jun 2022
Interview
Take Home Test => Phone Interview => Final round virtual interview
Take Home Test consists of 2 questions (1 easy, 1 more difficult) and some character fit questions.
Final round virtual interview (4 hours with 1 hour break in between). 3 rounds were coding, with 1 system design.
Interview questions [1]
Question 1
Dynamic programming problems
And a problem around code cleanliness and refactoring.
Be prepared to practice a lot of Leetcode, some of these questions are exactly the same but reworded.
And constantly speak out loud with your thought process and ask them if you are going down the right path
Surprisingly easy — I expected tougher questions, but the coding round felt more like a warm-up. The main challenge was a DSA problem about counting islands in a 2D grid, which led to a discussion on DFS versus BFS and handling large grids. Funny enough, I had revisited that exact type of question while prepping on PracHub, which made me feel more confident. The interview wrapped up with a behavioral round, and I accepted an offer, but ultimately decided to decline it for another opportunity. Overall, it was a smooth experience.

Question 1
Number of Islands — given a 2D grid of '1's (land) and '0's (water), count the number of connected islands. Walk through DFS vs BFS, and discuss how to avoid revisiting cells (in-place mutation vs visited set) and what changes if the grid is huge and must stream from disk.
It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
Um teste de código online, se aprovado, vai para o loop. O loop é 4 entrevistas seguidas, duas em inglês e duas em português. 3 entrevistas técnicas de código, todas as 4 têm pergunta de liderança.
